Mark Zuehlke is pretty much the go to IMO for the Canadian Army. A list of his NWE Stuff is as follows
"The Juno Trilogy" - Normandy
Juno Beach - The D-Day Landings
Holding Juno - Talks about battles to defend the D-Day Beaches
Breakout from Juno - The Breakout from the Normandy beach head through to the closing of the Falaise Gap.
The Cinderella Campaign - His latest published book about the battles for the channel ports in late August - Mid September 1944
"The Victory Trilogy" - Late '44 - 1945
Terrible Victory - The Scheldt Estuary Campaign
Forgotten Victory - The Rhineland Campaign
On to Victory - The Liberation of the Netherlands
Fantastic writer and one of the best examples of how Canadian historians tend to do their research.
I'd also recommend Mark Milner's "Stopping the Panzers", it's a total reexamination of June 7, 8, 9 and how vital the battles of 3rd Canadian Division were in guaranteeing the success of D-Day. Terry Copps "Fields of Fire" and "Cinderella Army" are also mandatory reading for anyone who wants to know more about the Canadian Army in NWE.
Ironically enough, The Victory Campaign is actually really lacking as an account of the Canadians in WW2. You can read more about why in Milner's book.
Happy reading!
